Really Tough: Outdoor Electrodes for pH, cond., O2

Hach Langes portable HQD metres and intellical electrodes measure the classic electrochemical parameters pH, conductivity and dissolved oxygen, using the drift-free optical method LDO. What makes HQD special is the newly developed intellical sensors: They store all relevant parameters and transmit them digitally to the meter. Thus making them safe from interferences and allowing for cable lengths up to 30 m even for pH! Previously inaccessible measurement locations e.g. boreholes and bridges are now within reach. No need to draw a sample first. The waterproof outdoor electrodes (IP67) have a hull made from stainless steel and are suitable for the toughest challenge. Their weight prevents them from drifting on the surface in strong currents.
